Front Canard Wings

[Dean Lampe]

Those are great, Fran! That is the type of detail stuff that really sets you apart.

Lumpy is sending your oil cans, I talked to him today. He had to order them in first.

 

[Randy V]

Fran's got an excellent start on what I was planning and will probably buy Fran's parts and modify.

Here's what I had in mind (borrowing Fran's picture):

 

[Ron McCall]

I was thinking the exact same thing Big-Foot.

 

[Dalton Veitch]

OOh,
They look expensive. All that welding.

I like the ones Randy did. I want them.

 

[Fran Hall RCR]

have a look at the ones on the work bench...they are already shaped like that.......two styles ...look closely

 

[Bill D]

Great! PM me the cost for the smaller ones like Randy's pic.

THOSE will really make my car look mean!!

 

[Fran Hall RCR]

Bill...
your car already looks mean....

 

[Randy V]

Fran - You're right - I did not look close enough at your semi-finished materials on the bench. The contour I have I think is a little different but accomplishes basically the same thing..

I've also been thinking about actually continuing the winglets to an air-dam that goes all the way across the "chin" of the car for trackdays / competition.
I know my Cobra is totally worthless in the handling department over about 135 without the air-dam. Never having driven a GT40, I'm not qualified to speak to the aero issues the car may have but the advent of the Mirage and some of the things they added to it such as the winglets / canards speak to someone's concern.

Thoughts?

Hi Fran

Your canards look a very good interpreatation of what I have seen elsewhere. Can you confirm that I am right in thinking that the thickness of the ali plate (more than 1/16 inch by the look of it) is increased to prevent flex etc as the plane of the canard is flat instead of curved and has no end plate, for a want of a better word?

Anyone got an opinion on the speed you need to be doing before canards actually give downforce?

 

[Randy V]

Anyone got an opinion on the speed you need to be doing before canards actually give downforce?

I believe that they will start adding both downforce and drag almost immediately but that it would take speeds higher than 80mph before they would make a noticeable difference.

Not that the body styles are even remotely comparable - I can tell you that the front air-dam on my Cobra made a measureable difference above 80mph. It also knocked off 5-7mph off the terminal velocity of the car.

 

[David Morton]

Both lift and drag vary with Speed squared (V²). Incidence (angle?) of the canard is a key factor on how much down force it will effect.
Is it a case of "Monkey see - Monkey do" because IMHO there are so many variables to take into account such as integrity of mounting, ride heights, dampers, springs and so on - is it worth it .

where am I going to put the kitchen sink now.???

Fran,

I would caution you about asking such an open-ended question with this type of audience. You may not like the answers people give you!! :lol:

Had to get that in.... Back to the garage.

Ciao!

 

[Peter Jankovskis]

We just did some aluminum canards for a Lola in the shop...
I will post pics tomorrow....

Hi Fran,

Are those the canards for my car?

 

[Lynn Larsen]

Guys,

I know that this discussion arose from a Superformance purchaser looking for something that wasn't provided by Superformance at the time, but I would respectfully suggest that it has developed far beyond that.

I think it would be appropriate to continue the discussion in the RCR forum and not here.

Lynn

 

[Fran Hall RCR]

Thanks Lynn

 

[Kim Petersen]

Fran:

Do you know yet whether your smaller profile canards will fit the SPF Mk I? If so, what price are you asking for a pair and what is the delivery time?

Thanks!

Kim

 

[Fran Hall RCR]

Kim,
we have a few sets on the shelf....

I cannot say that the RCR profile will be exactly correct for your SPF but if you want to provide me with a template profile , we can certainly make you some in short order..feel free to call me at the shop anytime....
